Can you explain what an alar base reduction is? Does this help with the width of the nose at the base?

Ala are the nostril margins so alar base reduction is the same as nostril narrowing. Alar base reduction is done when the nostrils are wide or flared and often are necessary in African American noses although many other cultures and races need nostril narrowing as well.
